Abstract
A two-step self-assembly strategy
has been developed for the preparation of fullerene hierarchical architectures.
Typically, the precipitation method is utilized to synthesize the
initial fullerene microstructures, and subsequently a drop-drying
process is employed to facilitate the fullerene microstructures to
self-assemble into the final hierarchical structures. Overall, this
methodology is quite simple and feasible, which can be applied to
prepare fullerene hierarchical structures with different morphological
features, simply by choosing proper solvent. Moreover, the as-obtained
C<sub>70</sub> hierarchical structures have many superior properties
over the original C<sub>70</sub> microrods such as superhydrophobicity
and unique photoluminescence behaviors, promising their applications
as waterproof optoelectronics
